IMPROVEMENT IN HARVESTERS.

The Schedule referred to in these Lettei's Patent and making part of thesame.

Figure 2 represents the tongue, with Asickle-bar attached thereto by alug-plate.

Figures 4: and 5 represent ratcliet-and-pawl attachments.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of my mvcntion consists in lightening the draught of aharvester by attaching the cuttingapparatus to the rear of 'he tongue,in such manner that it can be raised by the weight ofthe driver upon theseat, and also by means ot' a hand-lever, which latter is so attached asto raise the tongue or draught-- pole, with its attachments,(sickle-bar, and parts in connection thcrewith,) vand hold the same. upoli' the ground, it being held hy a pin or ratchet.

In tig. 1., A is the tongue or draught-pole, which is shown passing fromfront to rear, through the guideway L L, which is bolted upon the frontof the frame M, thence through the curved bed-plate X, and back to therear of the machine, where the lug-plate B, which connects the tongue tothe cutting-apparatus, is fastened to it by; a bolt or bolts, l) b andthe supporting-bar O is likewise rigidly attached to the tongue .at thispoint, and at its other end flexibly attached to a collar upon thecrank-boi of the fly-wheel shaft, on the rear ofthe frame M.

C represents the cutter-bar, with shoe I), attached .by a hinged jointto the lug-plate l, as shown in E is'the seat for driver, n'iount-edupon the arm J, which arm is, flexibly attached to the curve of bed:plate N, at T. c

F is a connecting-rod, running from the crank G, of'the'liting-meclianism, to the arm J of the seat, where it is madeadjustable, by a series of holes through it for a bolt or pin passingint-o the seatarm.

The small shaft to whi vh the. crank (i is attached, passes through thetop of guide-way L L, and .at its other end, a segment, S, with grooveupon its periphery, is attached.

rlhis segment has abcaring-chain, c', attached near its upper angle,(runninguponits grooved edge,) conmeeting it with the tongue at thefront of thema.-

chine.

.lhe shaft of crank G has a presserfoot, K, attached to it, (workingrwithin the guide-way I. L,) acting automatically, its. use 'being to'keep the frame of the machine parallel with the surface 'of the ground.A

At the lower part of the segment b', the chain c is attached, and passeshaelt over the grooved pulley e, (upon the curved arlu r/,) to the rearot' the tongue, where it is attached to the lug-plate l5.

lhese bearing-chains support the weight' of the tongue, with itsattachments, when it is required to raise the same by the weight of thedriver upon the seat E, and also by the hand-leverH.

'llnl flexible attachment of the sulmortiug-bar O, to the collar ofthecrank-box, admits ofthe easy raising and lowering ofthe tongue, and itsattachments, by the lifting-meehmiism described.

The pinion-shaft@driven bythe drive-wheels W, has a bevel-wheel, 1),upon it, inst outsidey oftln` frame next' the outside drive-wheel, whichbevelwheel, has a ratchet-and|awl attachment on` cac-h 'side of it,working in combination with it, and so arranged-as to-allow eachdrive-wheel to run independent of the other, in turning, backing, &e.

'lhese ratchets and pawls are. so attached as'to nui-ke the whole verycompact.

The bevel-wheel [i meshes into a pinion upon the thv-'wheel shaft j',utits forward end, transmitting the.

power from t-lul drive-wheels W, through this shaft, to thecutting-apparatus.

A draught-rml, 1.', runs from the front ofthe frame, where it isattached, to the Yrear of the tongue, and is bolted to it and thelug-plate l. lhis` rod holds the tongue and cut-ting-apparatus inposition.-

llavingr thus described my invention,

l. The bed-plate N, construe-tial with a cnrve,'to admit of the passageand free play of the tongue, substantially as shown and described.

2. The combination of scat-support J, adjustable colmecting-rod F, crankG, and hand-lever -1[,ar ranged and .operating to raise thetonguemilitent-tingapparatus attached thereto, substantially as shownand described.

3. The combination of hand-lever H, segment S. crank Ur, guide-way L,and plesscr-tbot .-K,-oper ating Substantially as and for the purposedescribed.

4. .Ihe supporting-bar O, attached tlexibly, at one end to the collar ofthe box of the crank-slurf(` and, at the other end, rigidly to therearof the tongue and lug-plate B, substantially as shown and frame withthe rear of the tongue, (and its attachdescribed. ments,) to hold the`same in position, as shown and 5.
